Title: Improvements in or relating to apparatus for detecting variation of surface characteristics of objects
IPC: B07C5/342
Filed: 1951-07-19
Abstract: 730,177. Sorting photo - electrically. BAIGENT, G. M. July 21, 1952 [July 19, 1951], No. 17196/51. Class 40 (3). In sorting objects in response to light reflected from defective spots on their surface, a number of light-receiving means are directed at an illuminated object viewing position so that each means views a small area of the object and then conducts the light received separately to a light-responsive device through apparatus which so masks the beams successively that a constant amount of light is received by the sensitive device at any one time. As shown, objects to be sorted fall one at a time through an aperture in a housing of the type described in Specification 712,113, in which light reflected from three parts of the object is directed by lens housings 4 through light guides 5 to a " mixing " block 6 which spreads the illumination evenly over the sensitive surface of a photo-electric cell 7. Between the ends of the light guides and the block passes a perforated rotating plate 11, the apertures in which are of such a size and so spaced that unless a defect appears on the object under examination the total cell illumination remains constant as the plate rotates. Thus a small defect on the object under examination reduces the total cell illumination appreciably. The rotating plate may be replaced by a mirror drum or a Kerr cell or other device in which variation of an applied field causes variation of the transformer of a substance. Specifications 492,035 and 662,685 also are referred to.

Abstract: 702,034. Telescopes. BARR & STROUD, Ltd. June 15, 1950 [July 1, 1949], No. 17433/49. Class 97(1) A binocular telescope includes a binocular eyepiece and a pair of objective lenses at the objective end and one or both of two separate light beams from the target is or are inclined towards the telescope axis by first optical means to cause said beams to pass through one or more common lenses of the telescope with substantial overlap of the beams thereat, said beams being thereafter rendered parallel by second optical means. As shown in Fig. 3, light from an object is received by prisms 8 of the telescope which are arranged so that the beams emergent therefrom are relatively inclined and pass through separate objectives 9, the axes of which are also inclined to the telescopic axis. The light beams, after passing through collecting lenses 10, diverge so as to overlap at a lens 11 which refracts the rays of each beam so that the beam emerging from the right (or left) hand prism 8 enters the left (or right) hand prism system 13 and the eyepiece 14 associated therewith. The prism systems 13 consist of right angled prisms which reflect the beams into parallelism and step prisms which direct the beams into the eyepieces 14. In other forms (a) the beams emergent from prisms 8 are parallel and, after passing through objectives having their axes parallel to the telescope axis, are so deviated by refracting prisms that the beams overlap at lens 11; (b) one prism 8 and the objective 9 associated therewith is disposed on the telescope axis and the beam emerging from the other prism 8 is alone deviated by a refracting prism so that the two beams overlap at lens 11; this latter beam is also deviated after passing through lens 11 so as to enter one of the eyepiece prisms; (c) the beams emerging from prisms 8 and objectives 9 are parallel and are deviated by prismatic lenses so that they overlap at two axially spaced and parallel lenses 11, prismatic lenses also being provided in the path of each beam emerging from the second lens 11 so that the beams enter the separate eyepieces; the two sets of prismatic lenses may be replaced by refracting prisms and another set of refracting prisms may be provided between the two lenses 11. The prism systems 13 may be combined in one prism arranged so that the beam emerging from the right (or left) hand prism 8 enters the right (or left) hand eyepiece 14 giving orthostereoscopic vision.

Filed: 1964-04-28
Abstract: 1,096,413. Electric protective systems. ENGLISH ELECTRIC CO. Ltd. April 28, 1965 [April 28, 1964], No. 17653/64. Heading H2K. A distance protective arrangement comprises comparators 22, 23, each for comparing at least two input signals proportional to different vectorial quantities derived from the protected system and for producing intermediate signals dependent on the instaneous phase relationship of the input signals. The intermediate signals are applied to a third comparator 26 which produces an output signal when a predetermined phase relationship exists between the intermediate signals. The first comparator 22 also produces an output signal in response to a predetermined phase relationship between its input signals and either of the output signals from the comparators 22, 26 can effect the operation of a protective device, e.g. a circuitbreaker 17. If a fault occurs on the protected system within a first zone, the comparator 26 produces an output to trip the circuit-breaker 17 without delay, but if the fault is within a second zone and outside the first zone, the output of comparator 22 operates a timing circuit 24 which after a time delay modifies the output from a signal generator 21 supplying the comparator 23 to enable the comparator 26 to produce an output in response to the second zone fault. If, however, the fault occurs in a third zone, the output of the comparator 22 operates a timing circuit 25 which after a longer time delay provides a tripping signal for the circuit-breaker 17. The Specification describes and illustrates various relay characteristics.

[Class 38 (ii).] In an arrangement for converting polyphase A.C. at one frequency to single-phase A.C. at a lower frequency the input transformer Tr has a star connected secondary Q each phase of which is connected to two anodes of a rectifier G through the oppositely directed primary coils PI, P<1>1, &c. of a single-phase output transformer TII. The anodes are arranged in two groups, one group being connected to primaries P1, P2, &c. and the other group being connected to primaries P1, P<1>1. &c. A synchronously running distributer S controls the grids, each contact being connected to the control grids of two anodes, one in each group, phase displaced 180‹ so that although both grids are energized only one anode will conduct. The numbers of turns in the groups of primary windings P1 .. P6, P<1>1 .. P<1>6 are graded so that the voltages induced in the secondary Q1 conform approximately to a sine curve. The contacts are arranged on the distributer so that in each half cycle one anode (the anode commencing the half cycle) conducts twice ; in the example shown in the drawing each half wave will be composed of seven loops. The cathode of the rectifier G is connected to the star point of secondary Q through a choke D which damps down current surges. The Specification describes a construction of the transformer TII in which the primary winding, composed of disc-shaped coils, is arranged inside and outside a cylindrical secondary winding.
